<p><strong>Abstract.</strong> Latvia currently is self-sufficient in energy resources up to approximately 35<span class="thinspace"></span>%. Annual fossil energy prices rise and risks of security of energy supply promote the development legislation in the matter of renewable resources. One of the Latvian Ministry of Economics' recent products is a new draft law called the "Renewable Energy Law", which has been created due to one of the European Union and Latvian national energy policy objectives: to increase the share of renewable energy up to 40<span class="thinspace"></span>% by 2020 (Moore and Vanags, 2012). Currently, geothermal energy potential is assessed at 1 × 1013<span class="thinspace"></span>kWh; nevertheless, it is difficult for geothermal energy to compete with other renewable energy resources in the Latvian energy market. A great job has been done in recent years at the legislative branch to choose the right methods for supporting the use of renewable energy resources. This paper aims is analysis of current situation and assessment of Latvian legislation possibilities to promote the use of geothermal energy.</p>

The use of renewable energies has a long past, even though its share of the total energy use is rather low in European terms. However, the tendencies are definitely favourable which is further strengthened by the dedication of the European Union to sustainable development and combat against climate change. The European Union is on the right track in achieving its goal which is to be able to cover 20% its energy need from renewable energy resources by 2020. The increased use of wind, solar, water, tidal, geothermal and biomass energy will reduce the energy import dependence of the European Union and it will stimulate innovation.

Exhaustion of traditional energy resources, their uneven geographical location, and catastrophic changes in the environment necessitate the transition to renewable energy resources. Moreover, Ukraine's economy is critically dependent on energy exports, and in some cases, the dependence is not only economic but also political, which in itself poses a threat to national security. One of the ways to solve this problem is the large-scale introduction and use of renewable energy resources, bioenergy in particular. The article summarizes and offers methods for assessing the energy potential of agriculture. In our country, a significant amount of biomass is produced every year, which remains unused. A significant part is disposed of due to incineration, which significantly harms the environment and does not allow earning additional funds. It is investigated that the bioenergy potential of agriculture depends on the geographical distribution and varies in each region of Ukraine. Studies have shown that as of 2019 the smallest share in the total amount of conventional fuel that can be obtained from agricultural waste and products suitable for energy production accounts for Zakarpattya region - 172.5 thousand tons. (0.5% of the total) and Chernivtsi region - 291.3 thousand tons. (0.9%). Poltava region has the greatest potential - 2652.2 thousand tons. (7.8%) and Vinnytsia - 2623.7 thousand tons. (7.7%). It should be noted that the use of the energy potential of biomass in Ukraine can be called unsatisfactory. The share of biomass in the provision of primary energy consumption is very small. For bioenergy to occupy its niche in the general structure of the agro-industrial complex, it is necessary to develop mechanisms for its stimulation. In addition, an effective strategy for the development of the bioenergy sector of agriculture is needed. The article considers the general energy potential of agriculture, its indicative structure. The analysis is also made in terms of areas. In addition, an economic assessment of the possible use of existing potential is identified.

In Australia the future demand for energy is predicted to increase rapidly. Conventional energy resources soaring prices and environmental impact have increased the interest in renewable energy technology. As a result of that the Australian government is promoting renewable energy; such as wind, geothermal, solar and hydropower. These types of energy are believed to be cost-effective and environmentally friendly. Renewable energy availability is controlled by climatic conditions such as solar radiation, wind speed and temperature. This paper aims to assess the potential of renewable energy resources, in particular wind and solar energy in an Australian subtropical region (Central and North Queensland) namely, Gladstone, Emerald, Rockhampton, Yeppoon, Townsville, and Cairns. Analysis is done by using the latest statistical state of Queensland energy information, along with measured data history of wind speed, solar irradiations, air temperature, relative humidity, and atmospheric pressure for those sites. This study has also shown that national assessments of solar and wind energy potential can be improved by improving local climatic data assessments using spatial databases of Central and North Queensland areas.

Abstract The development of the marine renewable energy and offshore aquaculture sectors is susceptible to being affected by climate change. Consequently, for the long-term planning of these activities, a holistic view on the effects of climate change on energy resources and environmental conditions is required. Based on present climate and future climate scenario, favourable conditions for wind and wave energy exploitation and for farming six marine fish species are assessed using a suitability index over all European regional seas. Regarding available energy potential, the estimated changes in climate do not have direct impacts on the geographic distribution of potential regions for the energy industry (both wind and wave based), that is they pose no threat to this industry. Long-term changes in environmental conditions could however require adaptation of the aquaculture sector and especially of its exploitation areas. Opportunities for aquaculture expansion of the assessed species are identified. Possibilities for co-location of these activities are observed in the different climate scenarios. The evaluation of potential zones for the exploitation of marine renewable energy resources and offshore aquaculture represents a stepping-stone, useful for improving decision-making and assisting in the management of marine economies both in the short-term and in the long-term development of these sectors.

As it is known, the utilization and production of renewable energy resources are very important in recent years. Due to its geological structural formations, Turkey has a serious geothermal energy potential as a renewable energy resource comparing with the other countries. West side of Turkey has also a critical role to use the geothermal energy resources. In these fields, geothermal is mostly used in electricity generation, greenhouse heating and locational requirements. The components while producing the geothermal water from wells such as heating pumps, re-injection pipes and other equipment are also significant. In this study, coefficient of performance (COP) utilizing in heat pumps has been investigated and the new approach to find out the parameter has been identified. Based on COP equation, the formula of COP has been re-coded on Dev C++ compiler by using C++ computer language in order to focus on the importance of computer aided applications in geothermal energy sector. There are no more studies showing the COP with C++ codes in literature. On the other hand, Germencik region, in the west side of Turkey, has been evaluated and the production processes by Guris Construction and Engineering Co. Inc. have been explained in the study. Moreover, the potential of Turkey has also been mentioned in this study. The aim of the study is to examine the Germencik region geothermal energy potential and to improve the coefficient of performance by using C++ in heat pumps. The result of this study shows us the Germencik region has an important potential and the computer aided technologies can also be adapted easily into the processes while producing geothermal energy.

Objectives : The world is getting more polluted day by day and living conditions are getting harder and harder. The Covid 19 process explains this situation even better. Global warming will show its effect more heavily if measures are not taken. There is a close relationship between global warming and the type and method of energy used. The use of fossil fuels by people pollutes the environment too much, and the use of alternative energy sources is gaining importance instead. Here, the issue of use and management of renewable energy sources comes to the fore. Turkey is a country with rich renewable energy resources and experience in cooperatives. In this study, it is aimed to reveal the current situation and problems of renewable energy cooperatives, which can be a model for managing Turkey’s renewable energy resources.Methods : In the study, a literature review method was used by examining domestic and foreign resources related to renewable energy and renewable energy cooperatives. Some of the data obtained were arranged in tables and used in the study.Results and Discussion : It is very important for Turkey to develop renewable energy resources and increase the share of renewable energy resources among other resources. Because Turkey is a developing country and its population is increasing day by day. It is essential to use renewable energy for the energy need of the increasing population and the least environmental pollution. Within the scope of 2023 targets in Turkey, it is planned to produce 34 thousand MW of hydroelectric, 20 thousand MW of wind energy, solar energy, 5 thousand MW, 1,000 MW of geothermal energy and 1,000 MW of geothermal energy and biomass energy. In order to achieve this goal, it is planned to invest approximately 60 billion dollars in renewable energy sources. Cooperatives are one of the most effective ways in which Turkey can use its renewable energy resources. Because cooperative is a method known to the Turkish society and it would be beneficial to transfer it to the renewable energy field.Conclusion : Turkey is a developing country and its energy needs are increasing day by day. It is very important to use the renewable energy resources it has correctly and in a planned way. In this respect, it should be understood that renewable energy cooperatives are quite compatible with Turkey. Turkey should provide the necessary legal and administrative structure for the development of renewable energy cooperatives and develop it with financial support in order to make its increasing energy needs sustainable.

Energy is a crucial factor in international relations and a critical input to achieve global economic growth and development. Provision of affordable, sustainable, and reliable energy is necessary and a prerequisite for any country’s economic growth and prosperity. The United Nations Agenda 2030, through its Seventh Sustainable Development Goal (SGD 7) and the African Union Agenda 2063 Aspiration 1recognise the centrality of access to energy towards realising the ambitions enlisted in these documents. The asymmetric distribution of natural resources and the political, strategic, financial, and technological challenges in utilising these resources hinder countries from availing affordable, sustainable, and reliable energy by using domestic sources alone. The inability to attain energy independence makes a compelling case for nations to increasingly integrate their energy supply chains to international and regional energy markets. As a result, ensuring access to affordable energy has become a core interest of regional foreign relations. Therefore, if geopolitics permits, energy cooperation and interdependence become the ultimate and sustainable path towards energy security. Africa has tremendous potential ranging from hydrocarbons to renewable energies. Nevertheless, it has failed to provide adequate energy for its social and economic needs mainly due to poor governance and related challenges. Africa has to utilise such humongous and diversified energy resources by embracing an optimal energy mix that contributes to regional economic development and energy integration. Eastern Africa, home to various renewable energy resources, is one of the energy-poor regions in Africa. The prevailing energy system in the sub-region is hydro-based and lacks reliability. The sub-region has tremendous renewable energy resources such as wind, solar, and geothermal. Still, their utilisation is negligible due to several challenges, including governance and lack of access to finance and technology. This paper argues that an integrated and regional approach to developing the energy sector in Eastern Africa can address the energy-related challenges and contribute towards regional integration in Eastern Africa. In particular, the development of geothermal energy, within the optimal energy mix in the sub-region, for both power generation and direct use application will play a crucial role in forging energy integration in Eastern Africa. In this regard, regional institutions such as power pools and regional economic communities are indispensable.   Received: 27 June 2021 / Accepted: 5 August 2021 / Published: 5 September 2021

Currently, many countries try to satisfy their energy needs with an increasing usage of renewable resources. The general motivations, with varying weighting in the different countries, are ecological reasons, concerns about energy security, and economical considerations. A for now rather theoretical question, although interesting for opening a long-term perspective, is how an energy supply from exclusively renewable energy resources could look like. This question has to be answered individually for any specific energy supply system. The present paper has the objective to present and evaluate a scenario for an electricity supply only from renewable energy resources for the Java-Bali grid. After designing a load time series for the year 2050 for the Java-Bali grid, a scenario is developed how to cover the load with electricity from renewable energy resources alone. Assumptions about the usable energy sources are made as well as assumptions about the available power plant capacity or energy potential. A specific challenge is the fact that solar energy must be the main source in such a renewable-energy based system, which comes with the need for a large storage capacity to match the power supply at any time with the load. Several possibilities are presented how to bring down the storage capacity: the increment of the installed PV capacity, the usage of bioenergy for seasonal balancing, and the complementation of the proposed short-term storage with an additional long-term storage. The study shows some of the specific challenges that a gradual transformation of the current electricity supply system on Java and Bali into a renewable-energy-based one would face and gives some hints about how to cope with these challenges. Scenarios like the one designed in this study are an important tool for decision-makers who face the task to scrutinize the consequences of choosing between different development paths. Article History: Received: August 15th 2017; Received: October 18th 2017; Accepted: January 14th 2018; Available onlineHow to Cite This Article: Günther, M., Ganal, I. and Bofinger, S.
